Table 1 Information on deployments and number of state-decoded hourly locations (number of state-decoded locations with complete dive data in parentheses) available for each beluga during the long-distance movement phase. Long-distance movement phase track length (km) is based on the (path) distance between consecutive CTCRW estimated locations for the fall and spring long-distance movements (i.e., sequence of locations outside the summer and winter residency areas) calculated using the geosphere v1.5-14 package [63] in R. This is a minimum estimate of travel distance as calculations are based on the shortest distance between consecutive points according to the ‘Vincenity (ellipsoid)’ method, and gaps ≤ 12.75 days were present between individual CTCRW track segments
